It should be appreciated thateach term, which is defined in a commonly used dictionary, should beinterpreted as having a meaning conforming to the relative skills andthe background or the context of the present disclosure, and should notbe interpreted in an idealized or overly formal manner unless definedotherwise.

Referring to FIGS. 1A and 1B, in an embodiment of the invention, theoptical member driving module 10 can be disposed in an electronic device20 and used to hold an optical member 30 (such as a lens). The opticalmember driving module 10 can drive the optical member 30 to moverelative to an image sensor module S in the electronic device 20, so asto achieve the purpose of focus adjustment and image stabilization. Forexample, the electronic device 20 can be a digital camera or a smartphone having the function of capturing photographs or making videorecordings. When taking photographs or recording video, the light canpass through the optical member 30, and the image sensor module S canreceive the light and form an image.

As shown in FIG. 2, the optical member driving module 10 primarilycomprises a housing 100, a movable mechanism 200, a plurality ofsuspension wires 300, and a base 400. The housing 100 and the base 400can be assembled and form a hollow box. The housing 100 surrounds themovable mechanism 200, and the movable mechanism 200 can be accommodatedin the hollow box. The housing 100 and the base 400 respectively have anopening O1 and an opening O2 corresponding to each other. The light canreach the image sensor module S through the opening O1, the opticalmember 30, and the opening O2 in sequence.

The movable mechanism 200 comprises an optical member holder 210, aframe 220, at least one first electromagnetic driving assembly 230, atleast one second electromagnetic driving assembly 240, a first elasticmember 250, and a second elastic member 260.

The optical member holder 210 has an accommodating space 211 and aconcave structure 212, wherein the accommodating space 211 is formed atthe center of the optical member holder 210, and the concave structure212 is formed on the outer wall of the optical member holder 210 andsurrounds the accommodating space 211. The optical member 30 can beaffixed to the optical member holder 210 and accommodated in theaccommodating space 211. The first electromagnetic driving assembly 230can be disposed in the concave structure 212.

The frame 220 has a receiving portion 221 and a plurality of recesses222. The optical member holder 210 is received in the receiving portion221, and the second electromagnetic driving assembly 240 is affixed inthe recess 222 and adjacent to the first electromagnetic drivingassembly 230.

The optical member holder 210 and the optical member 30 disposed thereoncan be driven by electromagnetic effect between the firstelectromagnetic driving assembly 230 and the second electromagneticdriving assembly 240 to move along the Z-axis relative to the frame 220.For example, in this embodiment, the first electromagnetic drivingassembly 230 can be a driving coil surrounding the accommodating space211 of the optical member holder 210, and the second electromagneticdriving assembly 240 can comprise at least one magnet. When a currentflows through the driving coil (the first electromagnetic drivingassembly 230), electromagnetic effect is generated between the drivingcoil and the magnet. Thus, the optical member holder 210 and the opticalmember 30 disposed thereon can be driven to move along the Z-axisrelative to the frame 220. The optical member holder 210 and the opticalmember 30 can be driven to move along the Z-axis relative to the imagesensor module S, and the purpose of focus adjustment can be achieved.

In some embodiments, the first electromagnetic driving assembly 230 canbe a magnet, and the second electromagnetic driving assembly 240 can bea driving coil.

As shown in FIG. 2, the first elastic member 250 and the second elasticmember 260 are respectively disposed on opposite sides of the opticalmember holder 210 and the frame 220, and the lens holder 210 and theframe 220 can be disposed therebetween. The inner portion 251 of thefirst elastic member 250 is connected to the optical member holder 210,and the outer portion 252 of the first elastic member 250 is connectedto the frame 220. Similarly, the inner portion 261 of the second elasticmember 260 is connected to the optical member holder 210, and the outerportion 262 of the second elastic member 260 is connected to the frame220. Thus, the optical member holder 210 can be hung in the receivingportion 221 of the frame 220 by the first elastic member 250 and thesecond elastic member 260, and the range of motion of the optical memberholder 210 in the Z-axis can be restricted by the first and secondelastic members 250 and 260.

Referring to FIG. 3, in this embodiment, the base 400 comprises a mainbody 410, a first wire 420, a second wire 430, and a coil assembly 440.The main body has a first surface 411, a second surface 412, and aplurality of openings 413. The first surface 411 is opposite to thesecond surface 412, and the second surface 412 faces the optical memberholder 210.

The first wire 420 and the second wire 430 are respectively formed onthe first surface 411 and the second surface 412, and respectivelyelectrically connected to the image sensor module S and the coilassembly 440. Similarly, when a current flows through the coil assembly440 via the second wire 430, electromagnetic effect is generated betweenthe coil assembly 440 and the second electromagnetic driving assembly240 (or the first electromagnetic driving assembly 230), and the opticalmember holder 210 and the frame 220 can move along the X-axis and/or theY-axis relative to the base 400. The optical member 30 can be driven tomove along the X-axis and/or the Y-axis relative to the image sensormodule S and the purpose of image stabilization can be achieved.

The first electromagnetic driving assembly 230, the secondelectromagnetic driving assembly 240, and the coil assembly 440 can forman electromagnetic driving mechanism, which is used to drive the movablemechanism 200 to move relative to the base 400.

In some embodiment, the main body 410 comprises an insulation plate. Thefirst wire 420 and the second wire 430 are directly formed on theinsulation plate by coating or using a molded interconnect device (MID).For example, the molded interconnect device can be laser directstructuring (LDS), microscopic integrated processing technology(MIPTEC), laser induced metallization (LIM), laser restructuring print(LRP), an aerosol jet process, or a two-shot molding method. In someembodiments, the main body 410 comprises a metal plate and insulationlayers disposed on the opposite surfaces of the metal plate. The firstwire 420 and the second wire 430 can also be formed on the insulationlayers directly by coating or using a molded interconnect device.

Referring to FIG. 3, the openings 413 are extended from the firstsurface 411 to the second surface 412, and the number and the positionof the openings 413 correspond that of the suspension wires 300. Thesuspension wires 300 can pass through the openings 413 and beelectrically connected to the first wire 420. The opposite ends of eachof suspension wires 300 are respectively affixed to the first elasticmember 250 and the first surface 411 of the main body 410 by the soldersR. Since the length of the suspension wire 300 exceeds or the same asthe distance between the first elastic member 250 and the base 400 plusthe thickness of the base 400, the suspension wire 300 can comprise alonger length in a limited space, compared to the suspension wire in theconventional lens driving module. The reduction of the optical memberdriving module 10 can be facilitated.

When the optical member holder 210 and the optical member 30 moves alongthe X-axis and/or the Y-axis, the range of the motion thereof can berestricted by the suspension wires 300. It should be noted that, asshown in FIG. 3, a gap is formed between the suspension wires 300 andthe inner wall of the openings 413. Therefore, the bending of thesuspension wires 300 due to the contact between the suspension wires 300and the inner wall of the openings 413 during the movement of theoptical member holder 210 can be avoided. Moreover, since the suspensionwires 300 comprise metal (for example, copper or an alloy thereof), thesuspension wires 300 can be used as a conductor, for example, thecurrent can flow into the first electromagnetic driving assembly 230through the base 400 and the suspension wires 300.

As shown in FIG. 2, in this embodiment, the optical member drivingmodule 10 further comprises a plurality of position detectors 500disposed on the base 400. The position detectors 500 can detect themovement of the second electromagnetic driving assembly 240 to confirmthe position of the optical member holder 210 and the optical member 30in the X-axis and the Y-axis. For example, the position detector 290 canbe a Hall sensor, a magnetoresistance effect sensor (MR sensor), a giantmagnetoresistance effect sensor (GMR sensor), a tunnelingmagnetoresistance effect sensor (TMR sensor), or a fluxgate sensor.

Referring to FIG. 4A, in another embodiment, the main body 410 of thebase 400 further comprises a depression portion 414, wherein thedistance between the bottom surface 414 a of the depression portion 414and the second surface 412 is less than that the distance between thefirst surface 411 and the second surface 412. It should be noted that,the distance between the bottom surface 414 a and the second surface 412in this embodiment is substantially the same as the distance between thefirst surface 411 and the second surface 412 in the embodiment shown inFIGS. 1-3. Thus, the length of the suspension wire 300 in thisembodiment can be increased.

As shown in FIG. 4B, when the optical member driving module 10 isconnected to the image sensor module S, at least a portion of the imagesensor module S can be accommodated in the depression portion 414. Thus,the whole thickness of the optical member driving module 10 and theimage sensor module S is maintained, the miniaturization of theelectronic device 20 can be facilitated.

Referring to FIG. 5, in another embodiment, the main body 410 of thebase 400 further comprises a lateral surface 417 and at least oneprotrusion 416. The lateral surface 417 is connected to the firstsurface 411 and to the second surface 412. The protrusion 416 isadjacent to the suspension wire 300 and protrudes from the first surface411. The end of the suspension wire 300 affixed to the first surface 411is disposed between the lateral surface 417 and the protrusion 416.Therefore, the protrusion 416 can prevent the solder R from flowing tothe center of the base 400 (or the depression portion 414), wherein theaforementioned solder R is used to affix the suspension wire 300. Theshort circuit owing to the contact between the image sensor module S andthe solder R when the optical member driving module 10 is connected tothe image sensor module S can be avoided.

Referring to FIG. 6, in another embodiment, the base 400 furthercomprises an inner wire 450 embedded in the main body 410. The firstwire 420 and the inner wire 450 are formed on the main body by insertmolding. The inner wire 450 is electrically connected to the second wire430.

As shown in FIGS. 7A-7C, in some embodiments, the first wire 420 can beformed by at least one metal sheet connected to the main body 410, andthe second wire 430 can be a flexible printed circuit (FPC) connected tothe main body 410. In some embodiments, the first wire 420 and thesecond wire 430 can be formed by disposing flexible printed circuits onthe opposite surfaces of the main body 410. In some embodiments, themain body 410 comprises a metal layer and insulation layers, wherein theinsulation layers are disposed on the metal layer. The first wire 420and the second wire 430 can be disposed on the insulation layers of themain body 410.

Referring to FIGS. 8A and 8B, in order to reduce the thickness of theoptical driving module 10, the base 400 in another embodiment comprisesa main body 410, a coil assembly 440, a first insulation layer 460, asecond insulation layer 470, a metal substrate 480, at, least one firstblocking member B1, and at least one second blocking member B2.

The main body 410 comprises a plurality of metal frames 415 separatedfrom each other, and has a plurality of extending portions 418 and aplurality of pins 419. The extending portions 418 are situated at fourcorners of the main body 410, extended toward the direction away fromthe movable mechanism 200, and comprise an L-shaped cross-section. Asshown in FIG. 8C, the bottom surface of the extending portion 418 is thefirst surface 411, and the surface of the metal frames 415 facing themovable mechanism 200 is the second surface 412. The extending portion418 is surrounded by the first blocking member B1. The end of thesuspension wire 300 can pass through the extending portion 418 and beaffixed to the first surface 411 by the solder R.

The stiffness of the extending portion 418 can be enhanced by the firstblocking member B1, so as to prevent the bending of the extendingportion 418 due to the pull of the suspension wire 418 during themovement of the frame 220 relative to the base 400. Furthermore, theshort circuit between the metal frames 415 due to the overflowing of thesolder R can also be prevented. In this embodiment, the first blockingmember B1 has a hollow structure, and a damping member D is disposed inthe hollow structure and covers a portion of suspension wire 300. Thus,the vibration of the suspension wire 300 during the movement of theframe 220 relative to the base 400 can be reduced.

Referring to FIGS. 8A and 8B, the pins 419 are extended toward thedirection away from the movable mechanism 200 such that the pins 419 canbe adjacent to and electrically connected to the image sensor module S.The metal frames 415 are formed on the first insulation layer 460. Theprojection area of the metal frames 415 on the first insulation layer460 exceeds 50% of the area of the first insulation layer 460.Therefore, the mechanical strength of the base 400 can be enhanced.Furthermore, a plurality of openings 461 are formed on the firstinsulation layer 460. The suspension wires 300 and the positiondetectors 500 can be connected to the metal frame 415 via the openings461.

As shown in FIG. 8D when the position detectors 500 are connected to themetal frames 415, the second blocking member B2 surrounds the connectingportion of the position detectors 500 and the metal frames 415.Similarly, a short circuit between the metal frames 415 due to theoverflowing of the solder can be prevented, wherein the aforementionedsolder is used to affix the position detector 500 to the metal frames415.

The second insulation layer 470 is disposed between the coil assembly440 and the main body 410. Similar to the first insulation layer 460, aplurality of openings 471 are formed on the second insulation layer 470.The suspension wires 300 and the coil assembly 440 can be connected tothe metal frame 415 via the openings 471.

The metal substrate 480 is connected to the first insulation layer 460,and the first insulation layer 460 is disposed between the main body 410and the metal substrate 480. The flatness of the main body 410 can beincreased by the metal substrate 480, and the metal substrate 480 can besoldered to the housing 100 to join the base 400 and the housing 100.

It should be noted that, the thickness of the first insulation layer 460is less than half of the thickness of the main body 410, and thethickness of the second insulation layer 470 is less than half of thethickness of the main body 410. Therefore, compared to the base whicharranged wires on the opposite surfaces of the insulation plate, thethickness of the base 400 in this embodiment is reduced. In someembodiments, the thickness of the first insulation layer 460 and thethickness of the second insulation layer 470 are less than the ¼ of thethickness of the main body 410. For example, the thickness of the mainbody 410 is 0.15 mm-0.20 mm, and the thickness of the first insulationlayer 460 and the thickness of the second insulation layer 470 are 0.01mm-0.03 mm.

In some embodiments, the second insulation layer 470 and/or the metalsubstrate 480 can be omitted as required, so as to reduce the thicknessof the base 400. In some embodiments, the insulation material can befilled between the metal frames 415 of the main body 415, and the coilassembly 440 and the second insulation layer 470 can be horizontallydisposed on the main body 410, wherein the insulation material isdifferent from the material of the first and second insulation layers460 and 470.

Referring to FIGS. 9A and 9B, in another embodiment, the base 400 canfurther comprise a third blocking member B3 surrounding the main body410 of the base 400. When the base 400 is joined to the housing 100, thesolder or the glue G can be disposed between the third blocking memberB3 and the housing 100. Therefore, the contacting area of the solder orthe glue G can be increased, and can prevent external objects fromentering.

As shown in FIG. 10, in another embodiment, the extending portion 418 ofthe main body 410 can be extended toward the movable mechanism 200 andhold the members of the movable mechanism 200, such as the secondelastic member 260.

In summary, an optical member driving module is provided. Since thesuspension wire of the optical member driving module extends through thebase, the suspension wire can comprise appropriate tension when thethickness of the optical member driving module is small. Furthermore,since the base of the optical member driving module comprises aplurality of metal frames, the thickness of the base can be reduced, andthe thickness of the optical member driving module can be reduced.
